Shortly after the outbreak of World War I, the Earl decided that it was necessary to make arrangements for the safeguarding of the succession and called upon his priests to elect a suitable candidate for the Episcopate. They elected the Reverened Frederick Willoughby, a former Anglican Clergyman, who was duly consecrated as recorded below, but whose connection with the Old Catholic Church in Great Britain was formally terminated on May 19, 1915 and he eventually submitted to Rome. Archbishop Mathew died on December 20, 1919, by which time the movement had become known as The Old Roman Catholic Church in Great Britain.
Thereafter a more pro-Roman policy was adopted. In 1914 a decision was made to restore the original Old Catholic as distinct from Old Roman Catholic basis and the following line of succession came into being:
- Arnold Harris Mathew, who on October 28, 1914, consecrated:
